What mass of steam initially at 150 degrees C is needed to warm 180 g of water in a 100 g glass container from 20.0 degrees C to 53.0 degrees C?
I have found the specific heats of the materials. I thought I should use Q=(m)(c)(delta T), but I can't figure out how to do that without the initial mass of the steam. Please help!

I realize that I won't be given what I'm trying to find. My problem is that I don't know how to begin looking for it.

The initial mass of the steam is the unknown you're supposed to solve for. That's why you're not given it!

Calculate the total energy needed to raise the water (and glass) from 20 to 53 C. Then find what mass of steam gives up that much energy when cooling from 150 C to 100C, condensing to water, and then cooling from 100 to 53 C.
